android - Fragment counterpart of getSupportFragmentManager -

is there counterpart of getsupportfragmentmanager fragments? or fragmentactivity?

i have this

adapter = new mypageradapter(this, this.getsupportfragmentmanager()); 

that goes here

public mypageradapter(topfrag context, fragmentmanager fm) {} 

fragment has method getfragmentmanager() returns fragmentmanager.
do:

adapter = new mypageradapter(this, this.getfragmentmanager());
