Method Details

textSegment

public TextSegment textSegment()

Specified by:

textSegment in interface Content

metadata

public Map<ContentMetadata,Object> metadata()

Specified by:

metadata in interface Content

equals

public boolean equals(Object o)

Compares this Content with another object for equality.
The metadata field is intentionally excluded from the equality check. Metadata is considered supplementary information and does not contribute to the core identity of the Content.

Overrides:

equals in class Object

hashCode

public int hashCode()

Computes the hash code for this Content.
The metadata field is excluded from the hash code calculation. This ensures that two logically identical Content objects with differing metadata produce the same hash code, maintaining consistent behavior in hash-based collections.

Overrides:

hashCode in class Object

toString

public String toString()

Overrides:

toString in class Object
