Class Format

    java.lang.Object
      org.jdom.output.Format

All Implemented Interfaces:
  java.lang.Cloneable

    public class Format

extends java.lang.Object
implements java.lang.Cloneable

Class to encapsulate XMLOutputter format options. Typical users can use the standard format configurations obtained by `getRawFormat()` (no whitespace changes), `getPrettyFormat()` (whitespace beautification), and `getCompactFormat()` (whitespace normalization).

Several modes are available to effect the way textual content is printed. See the documentation for `Format.TextMode` for details.

Method Detail

### getRawFormat

    public static Format getRawFormat()

  Returns a new Format object that performs no whitespace changes, uses the UTF-8 encoding, doesn't expand empty elements, includes the declaration and encoding, and uses the default entity escape strategy. Tweaks can be made to the returned Format instance without affecting other instances.

  Returns:
    a Format with no whitespace changes

### getPrettyFormat

    public static Format getPrettyFormat()

  Returns a new Format object that performs whitespace beautification with 2-space indents, uses the UTF-8 encoding, doesn't expand empty elements, includes the declaration and encoding, and uses the default entity escape strategy. Tweaks can be made to the returned Format instance without affecting other instances.

  Returns:
    a Format with whitespace beautification

### getCompactFormat

    public static Format getCompactFormat()

  Returns a new Format object that performs whitespace normalization, uses the UTF-8 encoding, doesn't expand empty elements, includes the declaration and encoding, and uses the default entity escape strategy. Tweaks can be made to the returned Format instance without affecting other instances.

  Returns:
    a Format with whitespace normalization

### setEscapeStrategy

    public Format setEscapeStrategy(EscapeStrategy strategy)

  Sets the `EscapeStrategy` to use for character escaping.

  Parameters:
    `strategy` - the EscapeStrategy to use
  Returns:
    a pointer to this Format for chaining

### getEscapeStrategy

    public EscapeStrategy getEscapeStrategy()

  Returns the current escape strategy

  Returns:
    the current escape strategy

### setLineSeparator

    public Format setLineSeparator(java.lang.String separator)

  This will set the newline separator (`lineSeparator`). The default is `\r\n`. To make it output the system default line ending string, call `setLineSeparator(System.getProperty("line.separator"))`.

  To output "UNIX-style" documents, call `setLineSeparator("\n")`. To output "Mac-style" documents, call `setLineSeparator("\r")`. DOS-style documents use CR-LF ("\r\n"), which is the default.

  Note that this only applies to newlines generated by the outputter. If you parse an XML document that contains newlines embedded inside a text node, and you do not set TextMode.NORMALIZE, then the newlines will be output verbatim, as "\n" which is how parsers normalize them.

  If the format's "indent" property is null (as is the default for the Raw and Compact formats), then this value only effects the newlines written after the declaration and doctype.

  Parameters:
    `separator` - `String` line separator to use.
  Returns:
    a pointer to this Format for chaining
  See Also:
    `setTextMode(org.jdom.output.Format.TextMode)`

### getLineSeparator

    public java.lang.String getLineSeparator()

  Returns the current line separator.

  Returns:
    the current line separator

### setOmitEncoding

    public Format setOmitEncoding(boolean omitEncoding)

  This will set whether the XML declaration (`<?xml version="1.0" encoding="UTF-8"?>`) includes the encoding of the document. It is common to omit this in uses such as WML and other wireless device protocols.

  Parameters:
    `omitEncoding` - `boolean` indicating whether or not the XML declaration should indicate the document encoding.
  Returns:
    a pointer to this Format for chaining

### getOmitEncoding

    public boolean getOmitEncoding()

  Returns whether the XML declaration encoding will be omitted.

  Returns:
    whether the XML declaration encoding will be omitted

### setOmitDeclaration

    public Format setOmitDeclaration(boolean omitDeclaration)

  This will set whether the XML declaration (`<?xml version="1.0"?gt;`) will be omitted or not. It is common to omit this in uses such as SOAP and XML-RPC calls.

  Parameters:
    `omitDeclaration` - `boolean` indicating whether or not the XML declaration should be omitted.
  Returns:
    a pointer to this Format for chaining

### getOmitDeclaration

    public boolean getOmitDeclaration()

  Returns whether the XML declaration will be omitted.

  Returns:
    whether the XML declaration will be omitted

### setExpandEmptyElements

    public Format setExpandEmptyElements(boolean expandEmptyElements)

  This will set whether empty elements are expanded from `<tagName/>` to `<tagName></tagName>`.

  Parameters:
    `expandEmptyElements` - `boolean` indicating whether or not empty elements should be expanded.
  Returns:
    a pointer to this Format for chaining

### getExpandEmptyElements

    public boolean getExpandEmptyElements()

  Returns whether empty elements are expanded.

  Returns:
    whether empty elements are expanded

### setIgnoreTrAXEscapingPIs

    public void setIgnoreTrAXEscapingPIs(boolean ignoreTrAXEscapingPIs)

  This will set whether JAXP TrAX processing instructions for disabling/enabling output escaping are ignored. Disabling output escaping allows using XML text as element content and outputing it verbatim, i.e. as element children would be.

  When processed, these processing instructions are removed from the generated XML text and control whether the element text content is output verbatim or with escaping of the pre-defined entities in XML 1.0. The text to be output verbatim shall be surrounded by the `<?javax.xml.transform.disable-output-escaping ?>` and `<?javax.xml.transform.enable-output-escaping ?>` PIs.

  When ignored, the processing instructions are present in the generated XML text and the pre-defined entities in XML 1.0 are escaped.

  Default: `false`.

  Parameters:
    `ignoreTrAXEscapingPIs` - `boolean` indicating whether or not TrAX ouput escaping PIs are ignored.
  See Also:
    `Result.PI_ENABLE_OUTPUT_ESCAPING`, `Result.PI_DISABLE_OUTPUT_ESCAPING`

### getIgnoreTrAXEscapingPIs

    public boolean getIgnoreTrAXEscapingPIs()

  Returns whether JAXP TrAX processing instructions for disabling/enabling output escaping are ignored.

  Returns:
    whether or not TrAX ouput escaping PIs are ignored.

### setTextMode

    public Format setTextMode(Format.TextMode mode)

  This sets the text output style. Options are available as static `Format.TextMode` instances. The default is `Format.TextMode.PRESERVE`.

  Returns:
    a pointer to this Format for chaining

### getTextMode

    public Format.TextMode getTextMode()

  Returns the current text output style.

  Returns:
    the current text output style

### setIndent

    public Format setIndent(java.lang.String indent)

  This will set the indent `String` to use; this is usually a `String` of empty spaces. If you pass the empty string (""), then no indentation will happen but newlines will still be generated. Passing null will result in no indentation and no newlines generated. Default: none (null)

  Parameters:
    `indent` - `String` to use for indentation.
  Returns:
    a pointer to this Format for chaining

### getIndent

    public java.lang.String getIndent()

  Returns the indent string in use.

  Returns:
    the indent string in use

### setEncoding

    public Format setEncoding(java.lang.String encoding)

  Sets the output encoding. The name should be an accepted XML encoding.

  Parameters:
    `encoding` - the encoding format. Use XML-style names like "UTF-8" or "ISO-8859-1" or "US-ASCII"
  Returns:
    a pointer to this Format for chaining

### getEncoding

    public java.lang.String getEncoding()

  Returns the configured output encoding.

  Returns:
    the output encoding

### clone

    public java.lang.Object clone()

  Overrides:
    `clone` in class `java.lang.Object`
