Parameters:

keys - the keys to render

Returns:

the CCL fragment

records

public static String records(List<Long> records)

Render a list of record identifiers as a CCL fragment. A single record is rendered bare; multiple records are rendered as a bracketed, comma-separated list.

Parameters:

records - the records to render

Returns:

the CCL fragment

value

public static String value(Object value)

Render a value as a CCL fragment. Strings are double-quoted with internal double quotes escaped; numbers and other types are rendered as their string representation.

Parameters:

value - the value to render

Returns:

the CCL fragment

values

public static String values(List<Object> values)

Render a list of values as a CCL fragment, enclosed in brackets.

Parameters:

values - the values to render

Returns:

the CCL fragment
