org.elasticsearch.script.ScriptType

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<ScriptType>, Writeable

public enum ScriptType
extends java.lang.Enum<ScriptType>
implements Writeable

ScriptType represents the way a script is stored and retrieved from the ScriptService. It's also used to by ScriptService to determine whether or not a Script is allowed to be executed based on both default and user-defined settings.

Enum Constant Detail

INLINE

public static final ScriptType INLINE

INLINE scripts are specified in numerous queries and compiled on-the-fly. They will be cached based on the lang and code of the script. They are turned off by default because most languages are insecure (Groovy and others), but can be overridden by the specific ScriptEngine if the language is naturally secure (Painless, Mustache, and Expressions).

STORED

public static final ScriptType STORED

STORED scripts are saved as part of the ClusterState based on user requests. They will be cached when they are first used in a query. They are turned off by default because most languages are insecure (Groovy and others), but can be overridden by the specific ScriptEngine if the language is naturally secure (Painless, Mustache, and Expressions).

Method Detail

values

public static ScriptType[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (ScriptType c : ScriptType.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static ScriptType valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null

readFrom

public static ScriptType readFrom(StreamInput in)
                           throws java.io.IOException

Reads an int from the input stream and converts it to a ScriptType.

Returns:

The ScriptType read from the stream. Throws an IllegalStateException if no ScriptType is found based on the id.

Throws:

java.io.IOException

writeTo

public void writeTo(StreamOutput out)
             throws java.io.IOException

Description copied from interface: Writeable

Write this into the StreamOutput.

Specified by:

writeTo in interface Writeable

Throws:

java.io.IOException

getId

public int getId()

Returns:

The unique id for this ScriptType.

getName

public java.lang.String getName()

Returns:

The unique name for this ScriptType based on the ParseField.

getParseField

public ParseField getParseField()

Returns:

Specifies the name used to parse input from queries.

isDefaultEnabled

public boolean isDefaultEnabled()

Returns:

Whether or not a ScriptType can be run by default. Note this can be potentially overridden by any ScriptEngine.

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Enum<ScriptType>

Returns:

The same as calling getName().
