    • DIRECTORY

      public static final Prop DIRECTORY
      File property "directory" is the path of the directory that the file variable maps to in this connection.

      The default value is the empty string; many tests use the "src/test/resources" directory; when launched via the morel shell script, the default value is the shell's current directory.

    • SCRIPT_DIRECTORY

      public static final Prop SCRIPT_DIRECTORY
      File property "scriptDirectory" is the path of the directory where the use command looks for scripts. When running a script, it is generally set to the directory that contains the script.

    • HYBRID

      public static final Prop HYBRID
      Boolean property "hybrid" controls whether to try to create a hybrid execution plan that uses Apache Calcite relational algebra wherever possible. Default is false.

    • INLINE_PASS_COUNT

      public static final Prop INLINE_PASS_COUNT
      Maximum number of inlining passes.

    • MATCH_COVERAGE_ENABLED

      public static final Prop MATCH_COVERAGE_ENABLED
      Boolean property "matchCoverageEnabled" controls whether to check the coverage of patterns. If true (the default), Morel warns if patterns are redundant and gives errors if patterns are not exhaustive. If false, Morel does not analyze pattern coverage, and therefore will not give warnings or errors.

    • OPTIONAL_INT

      public static final Prop OPTIONAL_INT
      Integer property "optionalInt" is for testing. Default is null.

    • RELATIONALIZE

      public static final Prop RELATIONALIZE
      Boolean property "relationalize" is whether to convert to relational algebra. Default is false.

    • STRING_DEPTH

      public static final Prop STRING_DEPTH
      Integer property "stringDepth" is the length of strings at which ellipsis begins.

      It is based upon the "stringDepth" property in the PRINTCONTROL signature of the Standard Basis Library. Default is 70.

    • LINE_WIDTH

      public static final Prop LINE_WIDTH
      Integer property "lineWidth" controls printing. The length at which lines are wrapped.

      It is based upon the "linewidth" property in the PRINTCONTROL signature of the Standard Basis Library. Default is 79.
