Constructor Detail

ConstructorStream

public ConstructorStream(RStream parent)

Method Detail

parent

public RStream parent()

Returns:

The parent stream

size

public int size()

Returns:

The amount of methods in this stream

opt

public java.util.Optional<ConstructorWrapper> opt(@Nullable
                                                  java.lang.Class<?>... parameterTypes)

Get a constructor by the given parameter types.

Parameters:

parameterTypes - The parameter types of the constructor

Returns:

The constructor wrapper

opt

public java.util.Optional<ConstructorWrapper> opt(int index)

Get a constructor by the given index.
The index is the position of the constructor in the stream.

Parameters:

index - The index of the constructor

Returns:

The constructor wrapper

by

public ConstructorWrapper by(@Nullable
                             java.lang.Class<?>... parameterTypes)

Get a constructor by the given parameter types.

Parameters:

parameterTypes - The parameter types of the constructor

Returns:

The constructor wrapper

Throws:

ConstructorNotFoundException - If the constructor doesn't exist

by

public ConstructorWrapper by(int index)

Get a constructor by the given index.
The index is the position of the constructor in the stream.

Parameters:

index - The index of the constructor

Returns:

The constructor wrapper

Throws:

ConstructorNotFoundException - If the constructor doesn't exist

filter

public ConstructorStream filter(java.util.function.Predicate<ConstructorWrapper> filter)

Filter the methods with the given filter.
The current stream will be modified.

Parameters:

filter - The filter

Returns:

This stream

filter

public ConstructorStream filter(@Nullable
                                java.lang.Class<?>... parameterTypes)

Filter the methods by the given parameter types.
The current stream will be modified.

Parameters:

parameterTypes - The parameter types of the constructor

Returns:

This stream

filter

public ConstructorStream filter(boolean isStatic)

Filter the constructors by whether they are static.
The current stream will be modified.

Parameters:

isStatic - Whether the constructor should be static

Returns:

This stream

filterAnnotation

public ConstructorStream filterAnnotation(java.lang.Class<?> annotation)

Filter the constructors by whether they have the given annotation.
The current stream will be modified.

Parameters:

annotation - The annotation

Returns:

This stream

iterator

public java.util.Iterator<ConstructorWrapper> iterator()

Returns:

An iterator of method wrappers

map

public <T> java.util.stream.Stream<T> map(java.util.function.Function<ConstructorWrapper,T> mapFunction)

Map the constructors to a new stream.
This is the same as calling jstream() and then Stream.map(Function).

Type Parameters:

T - The type of the new stream

Parameters:

mapFunction - The map function

Returns:

The new stream

jstream

public java.util.stream.Stream<ConstructorWrapper> jstream()

Returns:

A stream of method wrappers

forEach

public ConstructorStream forEach(java.util.function.Consumer<ConstructorWrapper> consumer)

Loop through all constructors in this stream.

Parameters:

consumer - The consumer

Returns:

This stream

copy

public ConstructorStream copy()

Returns:

A copy of this stream
