Field Detail

ANY_TYPE

static final int ANY_TYPE

A result set containing whatever type naturally results from evaluation of the expression. Note that if the result is a node-set then UNORDERED_NODE_ITERATOR_TYPE is always the resulting type.

Constant Field Values

ANY_UNORDERED_NODE_TYPE

static final int ANY_UNORDERED_NODE_TYPE

A result node-set containing any single node that matches the expression. The node is not necessarily the first node in the document that matches the expression.

See Also:

Constant Field Values

BOOLEAN_TYPE

static final int BOOLEAN_TYPE

A result containing a single boolean value. This is useful for example, in an XPath expression using the not() function.

Constant Field Values

FIRST_ORDERED_NODE_TYPE

static final int FIRST_ORDERED_NODE_TYPE

A result node-set containing the first node in the document that matches the expression.

See Also:

Constant Field Values

NUMBER_TYPE

static final int NUMBER_TYPE

A result containing a single number. This is useful for example, in an XPath expression using the count() function.

See Also:

Constant Field Values

ORDERED_NODE_ITERATOR_TYPE

static final int ORDERED_NODE_ITERATOR_TYPE

A result node-set containing all the nodes matching the expression. The nodes in the result set are in the same order that they appear in the document.

See Also:

Constant Field Values

ORDERED_NODE_SNAPSHOT_TYPE

static final int ORDERED_NODE_SNAPSHOT_TYPE

A result node-set containing snapshots of all the nodes matching the expression. The nodes in the result set are in the same order that they appear in the document.

See Also:

Constant Field Values

STRING_TYPE

static final int STRING_TYPE

A result containing a single string.

See Also:

Constant Field Values

UNORDERED_NODE_ITERATOR_TYPE

static final int UNORDERED_NODE_ITERATOR_TYPE

A result node-set containing all the nodes matching the expression. The nodes may not necessarily be in the same order that they appear in the document.

See Also:

Constant Field Values

UNORDERED_NODE_SNAPSHOT_TYPE

static final int UNORDERED_NODE_SNAPSHOT_TYPE

A result node-set containing snapshots of all the nodes matching the expression. The nodes may not necessarily be in the same order that they appear in the document.
