Method Detail

count

public static IntegerCondition count(java.util.List<StepCondition> steps)

Returns an integer condition that returns the number of the given conditions that evaluate to true.

This operation depends on Context.isShortCircuit(). It won't change the predicate value, but might impact performance and tree evaluation.

Parameters:

steps - the conditions to count

Returns:

the integer condition

matchAny

public static LogicalNaryCondition matchAny(java.util.List<StepCondition> steps)

Returns a nary condition that returns true if any of the given steps evaluate to true.

This operation depends on Context.isShortCircuit(). It won't change the predicate value, but might impact performance and tree evaluation.

Parameters:

steps - the conditions to match

Returns:

the nary condition

matchAll

public static LogicalNaryCondition matchAll(java.util.List<StepCondition> steps)

Returns a nary condition that returns true if all the given steps evaluate to true.

This operation depends on Context.isShortCircuit(). It won't change the predicate value, but might impact performance and tree evaluation.

Parameters:

steps - the conditions to match

Returns:

the nary condition

matchNone

public static LogicalNaryCondition matchNone(java.util.List<StepCondition> steps)

Returns a nary condition that returns true if none the given steps evaluate to true.

This operation depends on Context.isShortCircuit(). It won't change the predicate value, but might impact performance and tree evaluation.

Parameters:

steps - the conditions to match

Returns:

the nary condition

getMetadata

public Metadata getMetadata()

Description copied from interface: StepCondition

Returns the metadata to describe this node.

Specified by:

getMetadata in interface StepCondition

Returns:

the metadata

predicate

public java.util.function.BiPredicate<DslModel,Context> predicate()

Description copied from interface: StepCondition

Returns the predicate for this node value.

Specified by:

predicate in interface StepCondition

Returns:

the predicate

readable

public java.lang.String readable(java.util.Locale locale)

Description copied from interface: SyntaxTree

Returns the human readable version of this object.

Specified by:

readable in interface SyntaxTree

Parameters:

locale - the locale to use

Returns:

the readable string
