Method Detail

startsWith

public boolean startsWith(ByteSequence prefix)

Tests if this ByteSequence starts with the specified prefix.

Parameters:

prefix - the prefix.

Returns:

true if the byte sequence represented by the argument is a prefix of the byte sequence represented by this string; false otherwise.

concat

public ByteSequence concat(ByteSequence other)

Concatenate the given ByteSequence to this one.

Parameters:

other - string to concatenate

Returns:

a new ByteSequence instance

substring

public ByteSequence substring(int beginIndex)

Return the substring from ByteSequence, inclusive, to the end of the string.

Parameters:

beginIndex - start at this index

Returns:

substring sharing underlying data

Throws:

IndexOutOfBoundsException - if beginIndex < 0 or beginIndex > size().

substring

public ByteSequence substring(int beginIndex,
                              int endIndex)

Return the substring from beginIndex, inclusive, to endIndex, exclusive.

Parameters:

beginIndex - start at this index

endIndex - the last character is the one before this index

Returns:

substring sharing underlying data

Throws:

IndexOutOfBoundsException - if beginIndex < 0, endIndex > size(), or beginIndex > endIndex.

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toString

public String toString(Charset charset)

getBytes

public byte[] getBytes()

isEmpty

public boolean isEmpty()

size

from

public static ByteSequence from(String source,
                                Charset charset)

Create new ByteSequence from a String.

Parameters:

source - input String

charset - the character set to use to transform the String into bytes

Returns:

the ByteSequence
