Constructor Detail

Dependency

public Dependency()

Instantiates an empty Dependency.

Dependency

public Dependency(Source source,
                  Source dep_source)

Instantiates a Dependency between the two specified Sources.

Parameters:

source - a Source

dep_source - the dependent Source

Method Detail

hashCode

public int hashCode()

Return a hash code based on the source abbreviations.

Overrides:

hashCode in class Object

Returns:

a hash code based on the source abbreviations

equals

public boolean equals(Object o)

Returns true if the specified object is equal to this object. The specified object must be a Dependency with matching key fields.

Overrides:

equals in class Object

Parameters:

o - an Object to compare against

Returns:

boolean true if Object o is equal false otherwise

compareTo

public int compareTo(Object o)

Compares this Dependency to another one. Results are indeterminate if the specified parameter is not of the same class.

Specified by:

compareTo in interface Comparable

Parameters:

o - the Object to compare to

Returns:

int representing the relative ordering of this and the compare-to object

toString

public String toString()

Returns a String representation of the dependency.

Overrides:

toString in class Object

Returns:

a String representation of the dependency

getSource

public Source getSource()

Returns the Source object being depended upon.

Returns:

the Source object being depended upon.

setSource

public void setSource(Source source)

Sets the Source being depended upon.

Parameters:

source - the Source being depended upon.

getDependentSource

public Source getDependentSource()

Returns the dependent Source.

Returns:

the dependent Source

setDependentSource

public void setDependentSource(Source dep_source)

Sets the dependent Source.

Parameters:

dep_source - the dependent Source
