Constructor Detail

Equation

public Equation(String equation,
                Set<String> variableReferences,
                Map<String,Object> defaultVariableValues,
                Object[] code,
                int[] sourceLocations,
                Class<?> type)

Constructs an Equation.

Parameters:

equation - the string representing this equation

variableReferences - other variables that are referenced by this equation

defaultVariableValues -

code - the instruction sequence representing the compiled equation

sourceLocations - the starting points in the original equation for each node in the parse tree that resulted from the original equation

type - the type of the equation, String.class, Boolean.class or Double.class

Method Detail

toString

public String toString()

Returns a textual representation of an Equation.

Overrides:

toString in class Object

Returns:

this Equation as a String

equals

public boolean equals(Object other)

Compares one Equation to another.

Overrides:

equals in class Object

Returns:

true if this Equation is equivalent to "other" and else returns false

hashCode

public int hashCode()

Overrides:

hashCode in class Object

getVariableReferences

public Set<String> getVariableReferences()

Returns all the variable references that occur as part if this Equation.

Returns:

a set of variables referenced by this Equation

getDefaultVariableValues

public Map<String,Object> getDefaultVariableValues()

Returns default values for variable references, if any.

Returns:

a map of variable names to their default values, if any

getCode

public Object[] getCode()

Returns the compiled code (not Java byte code!) for the VM representing this Equation.

Returns:

the code representing this Equation

getSourceLocations

public int[] getSourceLocations()

Returns the starting points in the original equation for each node in the parse tree that resulted from the original equation. (Potentially useful for writing a debugger.)

Returns:

all the starting points in the original equation that resulted in parse tree nodes

getType

public Class<?> getType()

The overall type of the Equation, e.g. Long.class, String.class etc.

Returns:

the type of this
