Constructor Detail

FilteredAttributes

public FilteredAttributes(GPathResult parent,
                  Closure closure,
                  java.util.Map<java.lang.String,java.lang.String> namespaceTagHints)

Parameters:

parent - the GPathResult prior to the application of the expression creating this GPathResult

closure - the Closure to use to filter the attributes

namespaceTagHints - the known tag to namespace mappings

Method Detail

nodeIterator

public java.util.Iterator nodeIterator()

name

public java.lang.String name()

Description copied from class: GPathResult

Returns the name of this GPathResult.

Overrides:

name in class GPathResult

Returns:

the name of this GPathResult

childNodes

public java.util.Iterator childNodes()

Throws a GroovyRuntimeException, because attributes can have no children.

Returns:

an iterator over the child nodes of this GPathResult

iterator

public java.util.Iterator iterator()

parents

public GPathResult parents()

Throws a GroovyRuntimeException, because it is not implemented yet.

Returns:

the parents of this GPathResult

text

public java.lang.String text()

Description copied from class: GPathResult

Returns the text of this GPathResult as a String.

Returns:

the text of this GPathResult

list

public java.util.List list()

Description copied from class: GPathResult

Creates a list of objects representing this GPathResult.

Overrides:

list in class GPathResult

Returns:

a list representing of this GPathResult

findAll

public GPathResult findAll(Closure closure)

Description copied from class: GPathResult

Returns the children of this GPathResult matching the condition(s) specified in the passed closure.

Parameters:

closure - a closure to filters the children of this GPathResult

Returns:

the children matching the closure

writeTo

public java.io.Writer writeTo(java.io.Writer out)
                       throws java.io.IOException

Description copied from interface: Writable

Writes this object to the given writer.

This is used to defer content creation until the point when it is streamed to the output destination. Oftentimes, content will be defined but not necessarily created (as is may be the case with a Closure definition.) In that case, the output is then 'deferred' to the point when it is serialized to the writer. This class may be used whenever an object should be responsible for creating its own textual representation, but creating the entire output as a single String would be inefficient (such as outputting a multi-gigabyte XML document.)

Specified by:

writeTo in interface Writable

Parameters:

out - the Writer to which this Writable should output its data.

Returns:

the Writer that was passed

Throws:

java.io.IOException - if an error occurred while outputting data to the writer

build

public void build(GroovyObject builder)

Specified by:

build in interface Buildable

size

public int size()

Description copied from class: GPathResult

Returns the size of this GPathResult.

Specified by:

size in class GPathResult

Returns:

the size of this GPathResult

find

public GPathResult find(Closure closure)

Description copied from class: GPathResult

Returns the first child of this GPathResult matching the condition(s) specified in the passed closure.

Specified by:

find in class GPathResult

Parameters:

closure - a closure to filters the children of this GPathResult

Returns:

the first child matching the closure

replaceNode

protected void replaceNode(Closure newValue)

Specified by:

replaceBody

protected void replaceBody(java.lang.Object newValue)

Specified by:

replaceBody in class GPathResult

appendNode
