Enum 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

      • 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().
