public ByteArrayCharSequenceAdapterImpl()

Method Details

toCompressedString

@NotNull
public @NotNull CompressedString toCompressedString()

Description copied from interface: StringCompatible

Convert this StringCompatible into a CompressedString. Implementations should not cache result CompressedStrings, in order to avoid inadvertently allowing promotion of short-lived objects under generational garbage collection.

Returns:

A newly constructed CompressedString representing the same sequence of characters as this StringCompatible (or this object, if appropriate).

toMappedCompressedString

@NotNull
public @NotNull MappedCompressedString toMappedCompressedString()

Description copied from interface: StringCompatible

Convert this StringCompatible into a MappedCompressedString. Implementations should not cache result CompressedStrings, in order to avoid inadvertently allowing promotion of short-lived objects under generational garbage collection.

Returns:

A newly constructed MappedCompressedString representing the same sequence of characters as this StringCompatible (or this object, if appropriate).

set

public final ByteArrayCharSequenceAdapterImpl set(byte[] byteArray,
 int offset,
 int length)

Set the byte array backing this CharSequenceAdapter.

Parameters:

byteArray - A byte[] instance that contains a proto-String this adapter knows how to convert.

offset - The index of the first char in byteArray that belongs to the proto-String.

length - The length of the proto-String in chars.

Returns:

This CharSequenceAdapter.

clear

public final ByteArrayCharSequenceAdapterImpl clear()

Description copied from class: CharSequenceAdapter

Prepare this adapter for re-use, and eliminate references to external resources.

Specified by:

clear in class CharSequenceAdapter

length

public final int length()

charAt

public final char charAt(int index)
