Package se.kuseman.payloadbuilder.api.execution

Class UTF8String

java.lang.Object

se.kuseman.payloadbuilder.api.execution.UTF8String

All Implemented Interfaces:

Comparable<UTF8String>, ValueVector

public class UTF8String
extends Object
implements Comparable<UTF8String>, ValueVector

A bytes reference used for data types that supports operations directly on under laying byte structures like Strings etc. NOTE! ValueVector is implemented here to let a single string become a literal value vector of it self to avoid creating a literal

Method Details

getBytes

public byte[] getBytes()

Return a copy of the underlying utf8 bytes for this string

getBytes

public void getBytes(byte[] destination)

Return the bytes of this instance into destination byte array. Caller is responsible for correct length

size

public int size()

Description copied from interface: ValueVector

Return size of vector

Specified by:

size in interface ValueVector

type

public ResolvedType type()

Description copied from interface: ValueVector

Return type of vector values

Specified by:

type in interface ValueVector

isNull

public boolean isNull(int row)

Description copied from interface: ValueVector

Return if value at provided row is null

Specified by:

isNull in interface ValueVector

getString

public UTF8String getString(int row)

Description copied from interface: ValueVector

Get string at provided row.

Specified by:

getString in interface ValueVector

compareTo

public int compareTo(UTF8String that)

Compare this reference to another bytes reference

Specified by:

compareTo in interface Comparable<UTF8String>

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

hasString

public boolean hasString()

Returns true if this instance has a String instance.

getByteLength

public int getByteLength()

Return the byte length of this instance.

toString

public String toString()

Return a string representation of this instance

Overrides:

toString in class Object

concat

public static UTF8String concat(List<UTF8String> strings)

Concats provided string with a comma delimiter

concat

public static UTF8String concat(UTF8String delimeter,
 List<UTF8String> strings)

Concats provided string with a delimiter

from

public static UTF8String from(Object object)

Creates a string from provided object. Will fallback to toString if no known type is found

from

public static UTF8String from(boolean value)

from

public static UTF8String from(String string)

utf8

public static UTF8String utf8(byte[] bytes)

utf8

public static UTF8String utf8(byte[] bytes,
 int offset,
 int length)

latin

public static UTF8String latin(byte[] bytes)

latin

public static UTF8String latin(byte[] bytes,
 int offset,
 int length)

Create a utf8 string from latin encoded bytes. NOTE! Recommended usage is utf8 since this method allocates some when converting bytes.
