- Enum Constant Detail
  - 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.
  - PRINT_DEPTH
```
public static final Prop PRINT_DEPTH
```
    Integer property "printDepth" controls printing. The depth of nesting of recursive data structure at which ellipsis begins.
    It is based upon the "printDepth" property in the PRINTCONTROL signature of the Standard Basis Library. Default is 5.
  - PRINT_LENGTH
```
public static final Prop PRINT_LENGTH
```
    Integer property "printLength" controls printing. The length of lists at which ellipsis begins.
    It is based upon the "printLength" property in the PRINTCONTROL signature of the Standard Basis Library. Default is 12.
  - 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.

- Method Detail
  - values
```
public static Prop[] 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 (Prop c : Prop.values()) System.out.println(c);
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static Prop valueOf(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:
    
    IllegalArgumentException - if this enum type has no constant with the specified name
    
    NullPointerException - if the argument is null
  - lookup
```
public static Prop lookup(String propName)
```
    Looks up a property by name. Throws if not found; never returns null.
  - get
```
public Object get(Map<Prop,Object> map)
```
    Returns the value of a property.
  - booleanValue
```
public boolean booleanValue(Map<Prop,Object> map)
```
    Returns the value of a boolean property.
  - intValue
```
public int intValue(Map<Prop,Object> map)
```
    Returns the value of an integer property.
  - typeValue
```
private <T> T typeValue(Object o)
```
  - set
```
public void set(Map<Prop,Object> map,
                Object value)
```
    Sets the value of a property. Checks that its type is valid.
  - remove
```
public Object remove(Map<Prop,Object> map)
```
    Removes the value of this property from a map, returning the previous value or null.
