Class KeyspaceIdentifier

java.lang.Object

org.springframework.data.cassandra.core.cql.KeyspaceIdentifier

All Implemented Interfaces:

Comparable<KeyspaceIdentifier>

public final class KeyspaceIdentifier
extends Object
implements Comparable<KeyspaceIdentifier>

This encapsulates the logic for keyspace identifiers.

Keyspace identifiers are converted to lower case. To render, use any of the methods toCql(), toCql(StringBuilder), or toString().

Method Detail

ksId

public static KeyspaceIdentifier ksId(CharSequence identifier)

Deprecated. since 2.0, use of(CharSequence).

Factory method for KeyspaceIdentifier. Convenient if imported statically.

of

public static KeyspaceIdentifier of(CharSequence identifier)

Factory method for KeyspaceIdentifier. Convenient if imported statically.

Since:

2.0

isIdentifier

public static boolean isIdentifier(CharSequence chars)

Returns true if the given CharSequence is a legal keyspace identifier.

toCql

public String toCql()

Renders this identifier appropriately.

toCql

public StringBuilder toCql(StringBuilder sb)

Appends the rendering of this identifier to the given StringBuilder, then returns that StringBuilder. If null is given, a new StringBuilder is created, appended to, and returned.

toString

public String toString()

Alias for toCql().

Overrides:

toString in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object that)

Compares this KeyspaceIdentifier to the given object. Note that if a CharSequence is given, a new KeyspaceIdentifier is created from it and compared, such that a CharSequence can be effectively equal to a KeyspaceIdentifier.

Overrides:

equals in class Object

compareTo

public int compareTo(KeyspaceIdentifier that)

Specified by:

compareTo in interface Comparable<KeyspaceIdentifier>
