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 ByteBufferCharSequenceAdapterImpl set(ByteBuffer buffer,
 int offset,
 int length)

Set the ByteBuffer backing this CharSequenceAdapter.

Parameters:

buffer - A ByteBuffer instance that contains a proto-String this adapter knows how to convert.

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

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

Returns:

This CharSequenceAdapter.

clear

public final ByteBufferCharSequenceAdapterImpl 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)
