Class FilePredicateBuilder<T extends FilePredicateBuilder,Attributes extends FileAttributes>

java.lang.Object

org.mule.extension.file.common.api.FilePredicateBuilder<T,Attributes>

Type Parameters:

T - this instance concrete type. It allows to extend this class while allowing setter chains

Attributes - The concrete implementation of FileAttributes that this builder uses to assert the file properties

public abstract class FilePredicateBuilder<T extends FilePredicateBuilder,Attributes extends FileAttributes>
extends Object

Builds a Predicate which verifies that a FileAttributes instance is compliant with a number of criterias. This builder is stateful and not thread-safe. A new instance should be use per each desired Predicate.

This builder can either be used programmatically or through Mule's SDK since its internal state is annotated with the Parameter annotation.

Criterias are evaluated using an AND operator, meaning that for the predicate to accept a file, ALL the criterias must be complied with.

None of the criteria fields are mandatory. If a particular criteria is not specified, then it's simply not applied on the evaluation.

The class is also given the "matcher" alias to make it DSL/XML friendly.

Method Detail

build

public Predicate<Attributes> build()

Builds a Predicate from the criterias in this builder's state.

Returns:

a Predicate

addConditions

protected Predicate<Attributes> addConditions(Predicate<Attributes> predicate)

This method is invoked by build() before returning the built Predicate.

It allows extending classes to modify the returned Predicate.

Parameters:

predicate - the Predicate that is about to be returned by build()

Returns:

a new instance or the same one in case no modification is required.
