Method Details

get

public Map<String,String> get()
                       throws IllegalStateException

Merges and returns a map of all delegates this component holds. The merge strategy is implicitly set be the prior used instantiation of CompositePropertyIndexSupplier.Builder.

Specified by:

get in interface Supplier<Map<String,String>>

Returns:

a merged result map of all delegates

Throws:

IllegalStateException - in case builder() where used to instantiate the CompositePropertyIndexSupplier.Builder and the delegates contain duplicate keys.

• builder()
• keeping()
• overriding()

substituteValues

public PropertyIndexSupplier substituteValues(PropertyResolver resolver)

Description copied from interface: PropertyIndexSupplier

Creates an index supplier which substitutes every value contained by the underlying map.

Specified by:

substituteValues in interface PropertyIndexSupplier

Parameters:

resolver - the component that resolves system property

Returns:

new instance of a substituting index supplier

substitute

public UnaryOperator<String> substitute(PropertyResolver resolver)

Description copied from interface: PropertyIndexSupplier

Substitutes the entry's value.

Specified by:

substitute in interface PropertyIndexSupplier

Parameters:

resolver - the component that resolves system property

Returns:

a function which substitutes its argument

builder

public static CompositePropertyIndexSupplier.Builder builder()

using

public static CompositePropertyIndexSupplier.Builder using(BinaryOperator<String> mergeFunction)

Creates a new CompositePropertyIndexSupplier.Builder using the given merge function to handle duplicate keys during merge.

Returns:

a new instance of CompositePropertyIndexSupplier.Builder
