    • getEnableStringConversion

      public boolean getEnableStringConversion()
       Enable string conversion functions for CEL expressions. When enabled, CEL expressions
 can convert values to strings using the ``string()`` function.

 .. attention::

   This option is disabled by default to avoid unbounded memory allocation.
   CEL evaluation cost is typically bounded by the expression size, but converting
   arbitrary values (e.g., large messages, lists, or maps) to strings may allocate
   memory proportional to input data size, which can be unbounded and lead to
   memory exhaustion.
      bool enable_string_conversion = 1;
      Specified by:
      getEnableStringConversion in interface CelExpressionConfigOrBuilder
      Returns:
      The enableStringConversion.

    • setEnableStringConversion

      public CelExpressionConfig.Builder setEnableStringConversion(boolean value)
       Enable string conversion functions for CEL expressions. When enabled, CEL expressions
 can convert values to strings using the ``string()`` function.

   CEL evaluation cost is typically bounded by the expression size, but converting
   arbitrary values (e.g., large messages, lists, or maps) to strings may allocate
   memory proportional to input data size, which can be unbounded and lead to
   memory exhaustion.
      bool enable_string_conversion = 1;
      Parameters:
      value - The enableStringConversion to set.
      Returns:
      This builder for chaining.

    • clearEnableStringConversion

      public CelExpressionConfig.Builder clearEnableStringConversion()
       Enable string conversion functions for CEL expressions. When enabled, CEL expressions
 can convert values to strings using the ``string()`` function.

    • getEnableStringConcat

      public boolean getEnableStringConcat()
       Enable string concatenation for CEL expressions. When enabled, CEL expressions
 can concatenate strings using the ``+`` operator.

 .. attention::

   This option is disabled by default to avoid unbounded memory allocation.
   While CEL normally bounds evaluation by expression size, enabling string
   concatenation allows building outputs whose size depends on input data,
   potentially causing large intermediate allocations and memory exhaustion.
      bool enable_string_concat = 2;
      Specified by:
      getEnableStringConcat in interface CelExpressionConfigOrBuilder
      Returns:
      The enableStringConcat.

    • setEnableStringConcat

      public CelExpressionConfig.Builder setEnableStringConcat(boolean value)
       Enable string concatenation for CEL expressions. When enabled, CEL expressions
 can concatenate strings using the ``+`` operator.

      bool enable_string_concat = 2;
      Parameters:
      value - The enableStringConcat to set.

      This builder for chaining.

    • clearEnableStringConcat

      public CelExpressionConfig.Builder clearEnableStringConcat()
       Enable string concatenation for CEL expressions. When enabled, CEL expressions

    • getEnableStringFunctions

      public boolean getEnableStringFunctions()
       Enable string manipulation functions for CEL expressions. When enabled, CEL
 expressions can use additional string functions:

 * ``replace(old, new)`` - Replaces all occurrences of ``old`` with ``new``.
 * ``split(separator)`` - Splits a string into a list of substrings.
 * ``lowerAscii()`` - Converts ASCII characters to lowercase.
 * ``upperAscii()`` - Converts ASCII characters to uppercase.

 .. note::

   Standard CEL string functions like ``contains()``, ``startsWith()``, and
   ``endsWith()`` are always available regardless of this setting.

 .. attention::

   This option is disabled by default to avoid unbounded memory allocation.
   Although CEL generally bounds evaluation by expression size, functions such as
   ``replace``, ``split``, ``lowerAscii()``, and ``upperAscii()`` can allocate memory
   proportional to input data size. Under adversarial inputs this can lead to
   unbounded allocations and memory exhaustion.
      bool enable_string_functions = 3;
      Specified by:
      getEnableStringFunctions in interface CelExpressionConfigOrBuilder
      Returns:
      The enableStringFunctions.
