getLeafUnitNodes, getNodes

Method Detail

isLeafUnit

boolean isLeafUnit()

Checks whether the current ExpressionNode is a leaf unit. A leaf unit is a node with at least one leaf node as its child.

Returns:

A boolean value indicating whether the ExpressionNode is a leaf unit

getKind

ExpressionOperatorTypes.NODE_KIND getKind()

Returns the type of the filter expression. Some examples of filter expression types are unary, binary, literal, and so on.

Returns:

A enumeration value of type NODE_KIND indicating the type of the current node

isLiteralNode

default boolean isLiteralNode()

Checks whether the current node is a literal node.

Returns:

A boolean value indicating whether the current node is a literal

isPropertyNode

default boolean isPropertyNode()

Checks whether the current node is a property. For example, in the expression Name eq 'John', Name is the property.

Returns:

A boolean value indicating whether the current node is a property

hasProperty

default boolean hasProperty(String propertyName)

Checks whether the current ExpressionNode represents a filter on a certain property.

Parameters:

propertyName - Name of the property

Returns:

A boolean value indicating whether the current ExpressionNode represents a filter on the specified property

hasOperator

default boolean hasOperator(ExpressionOperatorTypes.OPERATOR operator)

Checks whether an operator is used in the current filter expression.

Parameters:

operator - Operator being searched in the filter expression

Returns:

A boolean indicating whether the operator is present in the current filter expression

hasFunction

default boolean hasFunction(ExpressionOperatorTypes.FUNCTION function)

Checks whether the current filter expression contains a function.

Parameters:

function - Function being searched in the filter expression

Returns:

A boolean value indicating whether the current filter expression contains the specified function
