org.apache.xpath.axes.PathComponent

Packages that use PathComponent
Package
Description
org.apache.xalan.transformer
In charge of run-time transformations and the production of result trees.
org.apache.xpath.axes
Implementation of XPath LocationPath support -- primary classes are LocPathIterator and UnionPathIterator.
org.apache.xpath.objects
Implementation of XPath polymorphic type objects -- this package will grow as XPath objects are expanded to support XML Schema data types.
org.apache.xpath.operations
Support for XPath operations, such as +, -, string(), etc.

  • Uses of PathComponent in org.apache.xalan.transformer

    Classes in org.apache.xalan.transformer that implement PathComponent
    Modifier and Type
    Class
    Description
    class 
    KeyIterator
    This class implements an optimized iterator for "key()" patterns, matching each node to the match attribute in one or more xsl:key declarations.
    class 
    KeyRefIterator
    This class filters nodes from a key iterator, according to whether or not the use value matches the ref value.

    Modifier and Type
    Class
    Description
    class 
    AttributeIterator
    This class implements an optimized iterator for attribute axes patterns.
    class 
    AxesWalker
    Serves as common interface for axes Walkers, and stores common state variables.
    class 
    BasicTestIterator
    Base for iterators that handle predicates.
    class 
    ChildIterator
    This class implements an optimized iterator for "node()" patterns, that is, any children of the context node.
    class 
    ChildTestIterator
    This class implements an optimized iterator for children patterns that have a node test, and possibly a predicate.
    class 
    DescendantIterator
    This class implements an optimized iterator for descendant, descendant-or-self, or "//foo" patterns.
    class 
    FilterExprIterator
     
    class 
    FilterExprIteratorSimple
    Class to use for one-step iteration that doesn't have a predicate, and doesn't need to set the context.
    class 
    FilterExprWalker
    Walker for the OP_VARIABLE, or OP_EXTFUNCTION, or OP_FUNCTION, or OP_GROUP, op codes.
    class 
    LocPathIterator
    This class extends NodeSetDTM, which implements NodeIterator, and fetches nodes one at a time in document order based on a XPath <a href="http://www.w3.org/TR/xpath#NT-LocationPath>LocationPath.
    class 
    MatchPatternIterator
    This class treats a LocationPath as a filtered iteration over the tree, evaluating each node in a super axis traversal against the LocationPath interpreted as a match pattern.
    class 
    NodeSequence
    This class is the dynamic wrapper for a Xalan DTMIterator instance, and provides random access capabilities.
    class 
    OneStepIterator
    This class implements a general iterator for those LocationSteps with only one step, and perhaps a predicate.
    class 
    OneStepIteratorForward
    This class implements a general iterator for those LocationSteps with only one step, and perhaps a predicate, that only go forward (i.e. it can not be used with ancestors, preceding, etc.)
    class 
    ReverseAxesWalker
    Walker for a reverse axes.
    class 
    SelfIteratorNoPredicate
    This class implements an optimized iterator for "." patterns, that is, the self axes without any predicates.
    class 
    UnionChildIterator
    This class defines a simplified type of union iterator that only tests along the child axes.
    class 
    UnionPathIterator
    This class extends NodeSetDTM, which implements DTMIterator, and fetches nodes one at a time in document order based on a XPath UnionExpr.
    class 
    WalkingIterator
    Location path iterator that uses Walkers.
    class 
    WalkingIteratorSorted
    This class iterates over set of nodes that needs to be sorted.

  • Uses of PathComponent in org.apache.xpath.objects

    Classes in org.apache.xpath.objects that implement PathComponent
    Modifier and Type
    Class
    Description
    class 
    XNodeSet
    This class represents an XPath nodeset object, and is capable of converting the nodeset to other types, such as a string.
    class 
    XNodeSetForDOM
    This class overrides the XNodeSet#object() method to provide the original Node object, NodeList object, or NodeIterator.
    class 
    XNull
    This class represents an XPath null object, and is capable of converting the null to other types, such as a string.

    Modifier and Type
    Class
    Description
    class 
    Variable
    The variable reference expression executer.
    class 
    VariableSafeAbsRef
    This is a "smart" variable reference that is used in situations where an absolute path is optimized into a variable reference, but may be used in some situations where the document context may have changed.
