Constructor Detail

NodeChildren

public NodeChildren(GPathResult parent,

                    Map<String,String> namespaceTagHints)

Parameters:

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

name - if the GPathResult corresponds to something with a name, e.g. a node

namespacePrefix - the namespace prefix if any

namespaceTagHints - the known tag to namespace mappings

Parameters:

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

name - if the GPathResult corresponds to something with a name, e.g. a node

namespaceTagHints - the known tag to namespace mappings

NodeChildren

public NodeChildren(GPathResult parent,
                    Map<String,String> namespaceTagHints)

Parameters:

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

namespaceTagHints - the known tag to namespace mappings

Method Detail

childNodes

public Iterator childNodes()

Description copied from class: GPathResult

Returns an iterator over the child nodes of this GPathResult.

Specified by:

childNodes in class GPathResult

Returns:

an iterator over the child nodes of this GPathResult

iterator

public Iterator iterator()

Specified by:

iterator in interface Iterable

Specified by:

iterator in class GPathResult

nodeIterator

public Iterator nodeIterator()

Specified by:

nodeIterator in class GPathResult

parents

public GPathResult parents()

Throws a GroovyRuntimeException, because it is not implemented yet.

Specified by:

parents in class GPathResult

Returns:

the parents of this GPathResult

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

text

public String text()

Description copied from class: GPathResult

Returns the text of this GPathResult as a String.

Specified by:

text in class GPathResult

Returns:

the text 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

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.

Specified by:

findAll in class GPathResult

Parameters:

closure - a closure to filters the children of this GPathResult

Returns:

the children matching the closure

build

public void build(GroovyObject builder)

writeTo

public Writer writeTo(Writer out)
               throws 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.)

Parameters:

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

Returns:

the Writer that was passed

Throws:

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

replaceNode

protected void replaceNode(Closure newValue)

Specified by:

replaceNode in class GPathResult

replaceBody

protected void replaceBody(Object newValue)

Specified by:

replaceBody in class GPathResult

appendNode

protected void appendNode(Object newValue)

Specified by:

appendNode in class GPathResult
