Tanvir Pathan's Blog: ADF-GROOVY : Use Java classes in groovy expressions

Today I will discuss about how you can use Java classes in groovy expressions. In this blog I will show you how you can access Private class fields, Protected class fields, Static class fields and Enums.

Here is the snippet of Bean.java

package com.tanvir.groovy.model.views;
 
public class Bean {
    private String privateJobId = "FI_ACCOUNT";
    protected String protectedJobId = "IT_PROG";
    public static String STATIC_JOB_ID = "PU_CLERK";
    
    public Bean() {
        super();
    }
 
    public void setPrivateJobId(String privateJobId) {
        this.privateJobId = privateJobId;
    }
 
    public String getPrivateJobId() {
        return privateJobId;
    }
 
    public void setProtectedJobId(String protectedJobId) {
        this.protectedJobId = protectedJobId;
    }
 
    public String getProtectedJobId() {
        return protectedJobId;
    }
}

Here is the snippet of JobIdEnum.java

package com.tanvir.groovy.model.utils;
  
public enum JobIdEnum {
    ST_CLERK("ST_CLERK"),
    SA_REP("SA_REP");
    
    private String jobId;
    
    private JobIdEnum(String jobId) {
        this.jobId = jobId;
    }
  
    public String toString() {
        return jobId;
    }
}

I have created one view criteria for each case and used bind variable to apply the groovy expression. Following are the groovy expressions for each case.
