Method Detail

append

public void append(E newE)

Appends an element to the Array

Specified by:

append in interface ArrayBuilder<E>

Overrides:

append in class ConstArray.Builder<E>

Parameters:

newE - the element to append

Throws:

java.lang.ClassCastException - if the newE is not immutable

java.lang.NegativeArraySizeException - if the resulting internal array would exceed the maximum length of a Java array. The builder is unmodified.

append

public void append(E[] newEs)

Appends all elements from a Java array to the Array

Specified by:

append in interface ArrayBuilder<E>

Overrides:

append in class ConstArray.Builder<E>

Parameters:

newEs - the element to append

Throws:

java.lang.ClassCastException - if the newEs is not immutable

java.lang.IndexOutOfBoundsException - if the resulting internal array would exceed the maximum length of a Java array. The builder is unmodified.

append

public void append(E[] newEs,
                   int off,
                   int len)

Appends a range of elements from a Java array to the Array

Specified by:

append in interface ArrayBuilder<E>

Overrides:

append in class ConstArray.Builder<E>

Parameters:

newEs - the source array

off - the index of the first element to append

len - the number of elements to append

Throws:

java.lang.ClassCastException - if the newEs is not immutable

java.lang.IndexOutOfBoundsException - if an out-of-bounds index would be referenced or the resulting internal array would exceed the maximum length of a Java array. The builder is unmodified.

snapshot

public ImmutableArray<E> snapshot()

Create a snapshot of the current content.

Specified by:

snapshot in interface ArrayBuilder<E>

Overrides:

snapshot in class ConstArray.Builder<E>

Returns:

an ImmutableArray containing the elements so far
